Don't know how you can address the trapazoid shaped windows with the bamboo shades.

Are the blinds for sun control, privacy ?

I wasn't planning on putting any window coverings on the windows with the fireplace. I do however, want to put the drapes (white) on the front and back windows, to the left and right of the fireplace wall. I'm not sure what height to put the drapes as the windows on all 3 walls are at different heights. If I hang the curtains up high on the back wall with the two separate windows to match the height of the beginning trapezoid, would it be too high???

No, the blinds are not for sun control, only to soften the room.

I would ignore the fireplace window height, and make the drapery heights of the back and front windows the same distance from the floor - which looks like right at the top of the window frame on the left, and between the frame and ceiling on the right. Then put the blinds inside the frames.

Thank you! I think that's what I'll do. That means that the two separate windows at the back will have the drapes hanging approx. 16" higher than the window molding but not quite as high as the fireplace windows. That's ok???

That is an excellent idea! Thank you!
